1. A game ball, comprising a foam material and housing:
a microcontroller connected to a power source, a motion switch, a sound generator and a vibration generator, the microcontroller incorporating or connected to a timer; whereupon movement of the game ball activates the motion switch to generate a signal to the microprocessor a) to start the timer for a first count period and to generate a first signal to the sound generator to emit a first series of sounds at a first interval; b) upon expiration of the first count period, to reset the timer for a second count period and to generate a second signal to the sound generator to emit a second series of sounds at a second interval being faster than the first interval; c) at the end of the second count period, to reset the timer for a third count period and to generate a third signal to the sound generator to produce a third series of beeps at a third interval being faster than the second interval; and d) upon said reset of the timer for the third count period, to generate a signal to the vibration generator to produce a vibrational motion at said third interval. |
